Specification forniingparifoflettrs PatentjNo. lsglslydated January 23, 1877 applica-tion iledV December 8,-1876u i 1 'j useful Improvement in Milk Pans and Cool ers, which improvement is fully set forthin `the following specication, reference being had to the accompanying drawing.

Our invention relates to that class of milk pans which are set in vats and cooled with cold water. A set of vats, four in number,

` fastened together, and forming at the upper surface arectangle, are mounted upon legs for the reception of the pans. Tin paus correspondin g to the size of these vats are placed in them, with the rim of the pans resting upon the upper edges of the vats, and supported underneath by a few rounded or beveled cross` pieces placed in the bottom of the vats.

In the drawing, Figure 1 represents a plan view, looking down upon the top of the pans placed in the vats. Fig. 2 represents a side view of the vats containing the pans. Fig. 3

A A represent the vats, and B B the pans. At the center or common corner of the four vats, water isintrod uced through a pipe into a common cylinder, C. This cylinder is provided with four stop-cocks, a a, and outletpipes, b b, each one of which runs down into its respective vat to the bottom, and extends along the inside lower edge of the vat` to the opposite end. Each of these pipes has` perforations along the whole length of the pan,

. so that when Water is turned on by means of t the stop-cock into any oneof the vats, it is distributed with a uniform temperature under the whole of the pan.

To regulate the depth ofthe water, and to supply an outlet thereto, an adjustable lateral pipe, c, is introduced into the outside and at the bottom of each vat.` This pipe is so arranged that it `can be raised and "lowered, and will remain in place at any altitude. This discharge-pipe can be These discharge-pipes o c are so `located the water flowing out falls into a tunnel, d, fastened to the sides of the vats, and is carried off through a pipe.

For the purpose of emptying the milk from the pans, a discharge-pipe, c, is secured to the bottom of each pan,`and extends downward through the vat. A short pipe, f, is fitted into and rmly secured to the bottom of the vat, and the discharge-pipe e extends `throughthe short pipe f. The short pipe f has a projecting shoulder rising a little above Vthe bottom of the vat, upon which rests a corresponding shoulder of the longer pipe e, which projects immediately below the bottom of the pan. The outside pipe or socketf has four or more flanges running down through it, with grooves between. The dischargepipe extends a little below the socket, closely litting against the anges, and has two small projecting ears, one upon each side of the projecting end. With suitable packing between the corresponding shoulders of the two pipes they may be made water-tight to prevent leakage of water out of the vat. This is done by means of a wrench or cam, D, mso constructed that it may be slipped over the end of the pipe e, and up against the socket f, `having two small inside grooves corresponding to the projecting ears of the pipe c.

Upon the inside ofthe cam are two flanges, each running half-way around on the principle of an inclined plane. These flanges catch upon the ears, and when the wrench is turned operate like the thread of a screw, drawing down upon the ears and pressing the shoulders firmly together. Between theadjoining ends of the four pans there is an open space, E E, down into the vats for the purposes of ventilation; and to still further promote u ventilation, and a free circulation of air when water isnot being used, orifices g g, of suf- `cient number, are made through the remote or cured to the upper edge ofl the inside partitions of the vats, and so made as to hold either one or two pans at the same time, as may be desired.

Another useful feature of our invention is that the legs F F are not permanently secured to the vats, but may be takenA olf and put on at pleasure, their upper ends being set in sockets h h, secured to the vats. Thus they may be made to occupy much less room when being shipped or not-in use.

We claim- 1. The pans B in vats A, with common cylinder C, and stop-cocks controlling perforated distributing-tubes, arranged as shown and described.v

2. The pans B and vats A, with movable discharging-pipes c and confluent tunnel d, substantially as arranged and described.

3. The pans B vats A, distributing perforated pipes b, and discharge-nozzles f and e, and tightening-cams D, arranged as described.

4. A cooler with pans B, heldin vats Aby a half headed button, i, and with ventilators g, as arranged and described.
